Featuring a body-mapped mix of synthetic and premium 850+ fill hydrophobic down insulations, the Marmot Ion 20 Degree sleeping bag ensures all-weather performance for cool-to-mild temperatures and does so at a weight of less than 2 pounds!
Extensive scientific research and testing to optimize body mapping of different insulation types resulted in the creation of Marmot’s family of Composite Bags. This unique construction combines certified 850+ fill power down treated with Marmot’s Down Defender water repellent treatment that allows the down to stay dry 10 times longer than untreated down in damp conditions with Marmot’s Thermal R Micro synthetic fill adding increased all-weather performance while keeping weight and bulk to a minimum. The down layer is situated within the top side of the bag to provide extra warmth to the core of the body while the synthetic insulation fills the back side of the bag to provide maximum warmth in compression zones between the body and the ground or sleeping pad.
Other features found in the Ion 20 Degree include a contoured, ergonomic hood that helps reduce heat loss and keeps your head warm and comfortable. A snagless draft tube sewn behind the full length zipper keeps cold air from reaching the inside of the sleeping bag and zippers from getting caught and creating damaging tears in the fabric. A “fold down” second zipper enables you to vent the bag when needed and also makes it easier to get in and out of the bag. An anatomically-designed footbox provides a more natural fit and improves warmth and comfort.
The Marmot Ion 20 Degree sleeping bag is available in Regular (fits up to 6' 0") and Long (fits up to 6' 6") lengths. A stuff sack and storage sack are included.
